1️⃣ Introduction

Mine rescue operations demand reliable and standardized breathing apparatus to ensure rescue personnel safety in oxygen-deficient or toxic atmospheres. As per the Mines Rescue Rules, 1985, all breathing apparatus used at rescue stations and rescue rooms must be of DGMS-approved make and type. However, under Rule 37 and Rule 11(4), special permission may be granted by DGMS to maintain and operate different types or makes of breathing apparatus at a rescue station — subject to proper testing, training, and maintenance provisions.

2️⃣ Legal Provisions

3️⃣ Objective of the Rule

• To ensure only safe, tested, and reliable breathing apparatus are used.
• To allow modernization and introduction of new models (Dräger, Siebe-Gorman, MSA, etc.).
• To maintain compatibility and interchangeability among equipment.
• To promote research and training using updated apparatus types.
• To prevent confusion in rescue operations due to multiple incompatible models.

4️⃣ Procedure for Obtaining DGMS Permission

1. Application by Owner/Manager: Submit detailed request to Director-General of Mines Safety through regional office. Include type, make, manufacturer details, and performance specifications.
2. Testing & Evaluation: Apparatus tested for performance, pressure, leakage, and breathing resistance at DGMS Testing Laboratory, Dhanbad.
3. Approval & Certification: DGMS issues written approval under Rule 37, mentioning type, serial number, and conditions of use.
4. Training Requirement: All rescue personnel must be trained in the operation, assembly, and maintenance of each apparatus type.
5. Record Keeping: Maintain apparatus register mentioning make, serial number, test dates, and DGMS permission number.
